I'm pleased to announce that Swift 1.9.0 has been released. This has
been a great release with major features added, thanks to the combined
effort of 37 different contributors.

Feature Summary
===============
Full global clusters support
----------------------------
With this release, Swift fully supports global clusters. A single
Swift cluster can now be deployed a wide geographic area (eg across an
ocean or continent) and still provide high durability and
availability. This feature has four major parts:
* Region tier for data placement
* Adjustable replica counts
* Separate replication network support
* Affinity on reads and writes
Improvements in disk performance
--------------------------------
The object server can now be configured to use threadpools to increase
performance and smooth out latency on storage nodes. Also, many disk
operations were reordered to increase reliablility and improve
performance. This work is a direct result of the design summit
sessions in Portland.
Support for config directories
------------------------------
Swift now supports conf.d style config directories. This allows config
snippets to be managed independently and composed into the full config
for a Swift process. For example, a deployer can have a config snippet
for each piece of proxy middleware.
Multiple TempURL keys
---------------------
The TempURL feature (temporary, signed URLs) now supports two signing
keys. This allows users to safely rotate keys without invalidating
existing signed URLs.
Other
-----
There's a ton of "other" stuff in this release including features,
security fixes, general polishing, and bug fixes. I encourage you to
